Froth flotation of copper sulphide ores

Froth flotation of copper sulphide ores. The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining for copper coating steel wire prior to wire drawing and in various copper plating processes The mining industry employs it as an activator in the concentration by froth flotation of lead zinc cobalt and

Improving reverse flotation of magnetite ore using

An improved performance was achieved using a pulse magnetic field during the reverse flotation of magnetite ore in a flotation column. The pulse magnetic field increased the recovery and grade of concentrate Fe by 1.12% and 4.22% respectively compared to the corresponding values obtained using no magnetic field.

Coal flotation. The Jameson Cell has been found to be particularly effective in cleaning and recovering fine coal particles. For example at BHP Coal's Goonyella mine (now part of the BHP Mitsubishi Alliance) eight Cells were installed to replace the entire 32 mechanical cell flotation circuit in 1995 in its 1800 t/h coal flotation plant.

US3596838A Flotation of sulphide ores Google

Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows.

Flotation is widely used to concentrate copper lead and zinc minerals which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

Structuring a Flotation Model for Robust Prediction of

The complexity of the flotation process has made the identification of an appropriate model structure for use in the prediction of flotation circuit performance far from obvious. Work performed under the auspices of the AMIRA P9 flotation program has indicated that the

Flotation of an Oxidized Copper Sulfide Ore

For each time interval a series of grinding flotation tests using different grinding media alloys was completed. The grinding and flotation chemistry were compared and linked to the flotation behaviour of the ore samples. The results reveal that as oxidation progressed the copper metallurgy deteriorated.

Froth flotation

For froth flotation the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic requiring little or no addition of collector).

The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5 15 weight percent of the ore feed (directly related to ore grade).

The processing of the test ore was problematic due to a mineral assemblage that caused prevalent slime generation.

A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27 1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers cone crushers and rod mills until it is reduced to less than 841 µm (20 mesh).
